SpringBoot Allow the application directory in an image built with buildpacks to be configurable

I want to change the app dir in the final output image built using SpringBoot Gradle Plugin's bootBuildImage task. The SpringBoot Gradle Plugin version is 3.0.5

and according to the gitter reply , it is not configurable yet. so please make it configurable.

Thanks.

The pack CLI has a --workspace option that enables this. The Spring Boot Gradle and Maven plugins could have an option named workspaceDir.
